Is my abnormal heart rhythm dangerous?

In this video, i tell you about those features which make an abnormal heart rhythm dangerous. The first is 1) How sustained the heart rhythm is 2) How fast the disturbance is 3) Is it atrial or ventricular 4) Is it on the background of an already damaged heart?
